Integration of Hot Gas Cleaning at Temperaures above the Ash Melting Point in Igcc

摘要

This paper gives two examples how a hot gas cleaning above the ash melting point,which has already been successfully demonstrated for the Pressurized Pulverized Coal Combustion Combined Cycle (PPCC),could be integrated in an IGCC with CO2 removal.The main advantage is the avoidance of slagging and fouling problems without the need for a gas quench.This is the prerequisite for the trouble-free operation of a highly efficient heat exchanger,a turbine,and a catalytic membrane,which offer the possibility of a significant increase in efficiency
